USB Relay Interface

The GBE USB relay allows a PC or Apple Mac to control a single external device using a relay contact attached to the USB port.

Simple for the programmer to use, the device appears as an additional COM port (network port on the Apple Mac) and can be easily interfaced into your code.

The relay is controlled by issuing commands to the port as if it was connected to a conventional serial (or network on the Mac) port. No technical knowledge of USB is required and no new driver interfaces need to be learnt.
